The ball valve operates through a quarter-turn mechanism. When manually or actuator operated, force applied to the lever or handle rotates the stem, which in turn positions the ball disc to either open or close the flow path.
- Open position: Lever perpendicular to flow, ball hollow aligned with media direction
- Closed position: Lever parallel to flow, ball solid blocking media passage
- Handle stop mechanism ensures precise quarter-turn operation
